Abstract: Methods and system for training a neural network for depth estimation in a vehicle. The methods and systems receive respective training image data from at least two cameras. Fields of view of adjacent cameras of the at least two cameras partially overlap. The respective training image data is processed through a neural network providing depth data and semantic segmentation data as outputs. The neural network is trained based on a loss function. The loss function combines a plurality of loss terms including at least a semantic segmentation loss term and a panoramic loss term. The panoramic loss term includes a similarity measure regarding overlapping image patches of the respective image data that each correspond to a region of overlapping fields of view of the adjacent cameras. The semantic segmentation loss term quantifies a difference between ground truth semantic segmentation data and the semantic segmentation data output from the neural network.

Abstract: A robotic system for use with a payload includes a robot, a passive compliance mechanism, position sensors, and an electronic control unit (ECU). Actuated joints of the robot provide the robotic system with actuated degrees of freedom (DOF). The compliance mechanism is connected to the robot and payload, and has unactuated joints providing the robotic system with unactuated DOF. The sensors measure joint positions of the joints. The ECU has a trajectory generator block which generates a payload trajectory signal in response to dynamic control inputs, and an impedance control unit (ICU) applying damping and stiffness parameters to the payload trajectory signal to generate an initial velocity command. A stiction compensation block allows the robotic system to generate a velocity offset, and applies the velocity offset to the initial velocity command to produce a final velocity command for the robot.
